In practice, one end porized distribution and flow ofthe metal is protion of the stock is heated to a temperature vided during the successive forming 'op'ersuflicient to facilitate the proper shaping of 30 at-ions, especially in shaping said hood porthe material. The firststep of my improved tions whereby accurately shaped and perfect method consists in fashioning the stock to 1y formed pairs of butt ay b r du d; form an'elongated and relatively thick blank and with these and other objects in view, the dy S ch as shown at 12 in Fig. 2 of the invention consists in a method of forming drawings, having arranged centrally of ophin b tts hich i m r full h r inaft r posite side edges thereof laterally projecting 85 described and claimed. extensions 13 which are arc-shaped or sub;

The invention is fully disclosed in the folstant'ially V-shapedin form, the contour of lowing specification, of which the accomthese extensions varying in the different types panying drawings form a part, in which the of products formed. The body 12 and the 4 separate parts of my improvement are desigextensions 13 remain intact with the bar nated by suitable reference characters in which provides a means of feeding or haneach of the views; and in which: dling the product in the further fashioning Fig. 1 is a perspective View of two diiferthereof.

Fig. 2' is a plan view showing thefirst step 2 between forming dies 14 and 15 to fashion of fashioning one end-of the stock. 7 the same into the shape seen in Fig. 3,,the

Fig. 3 shows the next step of fashioning ends 12a and 12b of the body 12 being anguthe stock to partially form the pairs of hinge larly and laterally disposed Whereas the but tsextensions 13 are drawn inwardly to form 109 walls or fillets between said angularly disposed ends and the crosshead 120 at opposite sides of the body 12.

The next step in forming the product consists in arranging the body 12 as formed in Figs. 3, 4 and 5 within and between forming dies 16 and 17, the operation of which will complete the general formation of the product to form a pair of hinge butts from the side portions 12a and 12b of the body 12', the crosshead 120 being depressed to form curved hood portions 18 arranged adjacent each other and joined by a connecting fin 20, and

side walls for the curved hood portion which are seen at 21 in Fig. 8 of the drawings. It will be noted at this time that the thickness of the side walls 21 is somewhat greater than the thickness of the body parts and hood portions of the respective butts, thus providing strong and durable bearing members for the pintle pins of the hinge, said side walls being drilled to form the apertures 22 for the pintle pins, this completing the forming operation of the separate butts, it being understood that the connecting fin 20 is removed and the removal of this fin forms on each butt at the termination of the curved hood portions 18, stop shoulders or walls 19. It will also be apparent that the joining part of the stock as seen at 23 in Fig. 6 of the drawings is sheared ofi' and removed after the formation of the pair of butt parts as seen in Fig. 6. The remaining end of the stock is then heated to form another pair of butts in accordance with the process above set forth, and this operation continues until the entire stock has been consumed, after which another bar or strip of stock is employed.

It will be apparent that by forming the hood portions from the central part of the workpiece disposed at the end of the bar 111 the manner set forth, and by utilizing dies having the wedge-shaped contour, tremendous power is available in the forming operation of the hood portions of the pair of butts, and this method of procedure also provides for the proper and easy flow of the metal during the shaping operations whereby the resulting products will be not only strong and durable but of a finished contour requiring no machine operations other than the possible removal of a flared metal which may prevail and the drilling or reaming of the pintle pin apertures in the side walls of f the hood portion of the butts. By virtue of my improved process, a hinge butt of the type under consideration which is stronger according to comparative tests than any other butt of its kind, regardless of the method of its manufacture, can be manufactured and sold at a price at least equal to most hinge butts of this class and cheaper than the more expensive hinges.

It will be understood that while I have diagrammatically illustrated certain die structures employed in forming pairs of hinge butts of specific contour, that my invention is not limited to the use of the specific arrangement of dies herein disclosed nor to the contour of the finished product or products and various other changes in and modifications of the method herein set forth may bemade within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
